Product Information
Full details
The SRAM GX X-HORIZON rear derailleur is designed for mountain bikers seeking precise and reliable 1x11 speed shifting. Its key benefit is smoother, faster shifts with reduced chain noise and fewer ghost shifts, thanks to its X-HORIZON design and ROLLER BEARING CLUTCH. A potential caveat is its specific compatibility with SRAM 1x drivetrains, limiting its use with other systems. This derailleur features technologies like X-ACTUATION for consistent shifting, X-SYNC pulley wheels for chain retention, and CAGE LOCK for easy wheel removal.

FAQs
Is this derailleur compatible with a 1x12 speed system?
No, the SRAM GX X-HORIZON rear derailleur is specifically designed for 1x11 speed systems. It is not compatible with 1x12 speed drivetrains.
What is the maximum cog size this derailleur can handle?
The long cage version of this derailleur is designed to work with a maximum rear cassette cog size of 42 teeth.
How do I clean the derailleur?
Use a degreaser and a soft brush to clean the derailleur body and pulley wheels. Wipe dry with a clean cloth. Avoid using high-pressure water directly on the bearings.
What does X-HORIZON technology do?
X-HORIZON technology minimizes the horizontal movement of the derailleur's outer cage, which reduces the force required for shifting, eliminates ghost shifting, and keeps chain slap to a minimum.
Can I use this derailleur with Shimano shifters?
No, this derailleur uses SRAM's X-ACTUATION cable pull ratio and is only compatible with SRAM 11-speed trigger shifters.
How does the ROLLER BEARING CLUTCH work?
The ROLLER BEARING CLUTCH engages a one-way roller clutch bearing that provides consistent chain tension, preventing the chain from bouncing excessively on rough terrain and reducing chain drop.
What is the purpose of CAGE LOCK?
CAGE LOCK is a feature that locks the derailleur cage in a forward position, making it significantly easier and faster to remove or install the rear wheel.
Troubleshooting
Ghost shifting (unwanted gear changes)
Check cable tension, ensure cable and housing are clean and well-lubricated, verify limit screw settings, and confirm compatibility with the shifter.
Chain dropping off cassette
Verify B-tension screw adjustment for correct pulley-to-cog gap. Ensure X-SYNC pulley wheels are clean and not worn. Check chain wear and condition.
Stiff or difficult shifting
Lubricate shifter cable and housing. Inspect for any kinks or damage to the cable. Ensure the derailleur hanger is straight.
Derailleur cage won't lock for wheel removal
Ensure the CAGE LOCK lever is fully engaged and clean. If it feels stiff, apply a light lubricant to the pivot points.
Excessive chain slap noise
Ensure the ROLLER BEARING CLUTCH is engaged (it should always be on for 1x systems). Check chain length and ensure it's appropriate for the drivetrain.

Setup, Compatibility & Care
Compatibility:
- Designed for SRAM 1x11 speed drivetrains only.
- Requires a compatible SRAM 11-speed trigger shifter.
- Maximum rear cassette cog: 42 teeth (long cage).
- Uses the standard derailleur hanger mount.
Setup:
- Mount the derailleur to the frame's derailleur hanger.
- Route the shifter cable through the CAGE LOCK mechanism (if disengaged) and connect it to the derailleur's cable anchor bolt.
- Set the initial cable tension using the barrel adjuster on the shifter or derailleur.
- Adjust the B-tension screw to ensure proper clearance between the upper pulley wheel and the cassette cogs.
- Perform limit screw adjustments to prevent overshifting off the largest and smallest cogs.
Care:
- Regularly clean the derailleur body and pulleys with a degreaser and brush. Ensure the CAGE LOCK lever is functioning smoothly.
- Inspect the derailleur cage for any bends or damage after impacts.
- Keep the cable and housing clean and lubricated for optimal shifting performance. Replace as needed.
- Periodically check the ROLLER BEARING CLUTCH for excessive play or noise.
